Chip Moves 4 months after installation

I did the vitamin thing and have been monitoring it. It seems to have settled in an area (that’s actually easier to read). It still moves a bit but I’m trying not to play with it. I recently lost a lot of weight. Could that have something to do with it? It’s weird, when I first start losing weight, I notice it in my hands and fingers before I see results. I’m OK where it is. I’m just going to stick to the vitamins. The question was for future reference as I plan on getting more.
